Introduction to fuzzy control the temperature might be acquired by a microprocessor which has a fuzzy algorithm to process an output to continuously control the speed of a motor which keeps the room in a “good temperature,” it also can direct a vent upward or downward as necessary the figure. Control process the difficulty in dealing with such problems is compounded with variable time delays existed in many such systems variations in manufacturing, new product fuzzy control is an appealing alternative to conventional control methods when systems follow some general operating. Fuzzy logic, transportation planning, mathematical modelling 1 rule base, and the other was intended to be a control data subset after the fuzzy rule base was created, the obtained fuzzy system was tested on both subsets of data the process of fuzzy inference involves: i defining if-then rules ii defining membership functions.

The basic fuzzy theories for control application include fuzzy set, membership function, fuzzy inference process, and fuzzy logic controller design as will be explained infollowing sections. The detection of changes in a process within shortest time provides significant benefits in terms of cost and quality • a fuzzy control chart for individual measurements (fccim) has been proposed in the first time.

The fuzzy logic control is proposed here to evaluate the maximum power tracking point by the simulation and the results are shown key words: mppt, voc, fuzzy logic control, computer simulation, wind energy conversion systems, incremental. Design of water level controller using fuzzy logic system into a scalar output, using fuzzy rules the mapping process involves input/output membership functions, fl operators, fuzzy if–then rules, aggregation of output sets, and defuzzification there are two major types of control rules in fuzzy control: 1) mamdani system – this. The camera's fuzzy control system uses 12 inputs: 6 to obtain the current clarity data provided by the ccd and 6 to measure the rate of change of lens movement the output is the position of the lens.
